IMPROVEMENT IN ADJUSTABLE SHELF-BRACKETS.

Specification forming part of Letters Patent No. 217,471, dated July 15,1879; application filed May 22, 1879.

To al whom it may concern:

Be it known that I, A. P. MASSEY, of Cleve land, in the county ofOuyahoga and State of Ohio, have invented certain Improvements inAdjustable Shelf-Brackets, ot'which the following is a specification.

The various methods of supporting shelves now in use involve either afixed position of shelves, or an adj ustability more or less awkward andlaborious in practice, and capable of varying the distances betweenshelves only by considerable degrees.

The object of my invention is to furnish a method by which this distancemay be conveniently and quickly graduated to any degree, and so securingwhat is found to be a desideratumthe greatest economy of space.

Figure 1 is a perspective side elevation of all the parts of my devicein position. Fig. 2 is a perspective view of a shelf-bracket detached.Fig. 3 is a plan view of the same, with the ends broken away.

A is the part of the bracket on which the shelf rests in position. B isa vertical metallic rod, to which the bracket is attached in the mannerhereinafter shown. C is a shelf, with part removed to show the operationof the device and D is the general casing of the shelving.

The bracket shown in Fig. 2 is made of malleable iron or other suitablemetal, having the rest A, the hook a, and the indenture c, the indentureand hook being made to fit and surround. the rod B, and sufiicient spacebeing left between the point of the hook at and rest A to enable the rodB to pass between them. This bracket may be made in pairs, the oneintended for one end of a shelf having its hook turned in one directionand the other having its hook turned in the opposite direction, as shownby the two brackets represented in the drawings.

It is obvious that when the bracket is placed in position with the rod,the shelf 0 resting on the part A, as shown in Fig. 1, the bracket takeshold of the rod by means of the described hook and indenture with abinding gripe, which holds the bracket securely in place at whateverelevation it is located, and that in order to adjust the bracket to anyelevation it is only requisite to raise and turn the part A upward to sorelease the bracket that it will readily slide up or down the rod, asrequired.

The rod B and the corresponding iudenture e are made, preferably, withroughened surfaces or screw-threads, as shown in the drawings, and thefitting of the rod into the hook and indenture should be closelyadjusted, so as to prevent the shelf from tipping.

It will be apparent, also, that in the use of this device any shelf andbrackets may be quickly removed, or additional ones interposed.

I claim as my invention- 1. The combination of the easel), rod B, shelf0, and bracket A, the latter provided with the hook a and indenture c,the indenture and hook being made to fit and embrace the rod,substantially as shown and described.

2. In combination with the rodB,the bracket A, With its hook a andindenture e, the indenture and hook being made to fit and embrace therod, substantially as shown and described.

ALBERT P. MAS SEY.
